8 Toning Black-and-White Materials • G-23
Save the remainder of Stock Solution B to replenish the
toning bath as you use it. The volume that you add will
depend on the number of prints you tone and the toning time.
For example, if you tone to a warm-brown hue, add 4 mL of
Stock Solution B after every fifty 8 x 10-inch prints (or
equivalent).
1. Place a tray in a tempered water bath. Pour the clear
toner solution into the tray, and heat the water to 43°C
(109°F). Maintain this temperature during toning.
2. Immerse a thoroughly washed print in the toning
solution for 5 to 20 minutes until it has the tone you
want. (It’s helpful to keep an untoned print on hand for
comparison.)
Note: Some sediment will form in the tray, especially if
you tone more than one print at a time. The sediment is
harmless, but it can form a scum on the print. If scum
forms, wipe the print with a wet sponge or wet cotton
immediately after toning.
3. Remove the print from the toner and rinse it in cold
water.
Wash fiber-base prints in running water at 18 to 24°C
(65 to 75°F) for one hour, or use Hypo Clearing Agent to
reduce the wash time; wash resin-coated prints for 4 minutes.
Gold Protective Solution GP-1
Prepare the solution as follows. For best results, mix it right
before you use it.
Gold Protective Solution GP-1
Add the 10 mL of gold chloride stock solution to the
750 mL of water. Dissolve the sodium thiocyanate solution
separately in 125 mL of water. Then slowly add the sodium
thiocyanate solution to the gold chloride solution while
stirring rapidly.
1. Immerse a thoroughly washed print in the solution at
20°C (68°F).
2. Treat the print for 10 minutes or until you can see a very
slight change to a bluish black in the image tone.
Wash fiber-base prints in running water at 18 to 24°C
(65 to 75°F) for 10 minutes; wash resin-coated prints for
4 minutes.

Gold chloride,
*
1% stock solution
†
* Gold chloride is a deliquescent chemical; it will liquefy rapidly in a
normal room atmosphere. Store the chemical in a tightly stoppered
bottle in a dry atmosphere.
† To prepare a 1% gold chloride solution, dissolve 1 gram of gold
chloride in 100 mL of water. Or you may want to obtain a 1-percent
solution from a photographic dealer.

Blue Toner T-26
The contrast and density of prints treated in Blue Toner T-26
appear to increase. You can compensate for these increases
by reducing the exposure time slightly when you make your
prints. The exact tone you obtain will vary with the paper and
developer you use. A soft gray-blue is more common than a
saturated blue.
Note: Blue Toner is fairly expensive toner to produce. For
best results, prepare the solution right before you use it. If
you tone prints one at a time in Blue Toner, the first few
prints will tone the most, and the last few may not tone at all.
To obtain consistent results, immerse up to five prints in the
bath simultaneously.
Mix the toner working solution as follows:
Blue Toner T-26
Stir until the chemicals dissolve completely.
Note: A fine white precipitate may appear in the solution if
you store it overnight. This precipitate will not interfere with
toning.
1. Immerse a thoroughly washed print in the toning
solution adjusted to 20°C(68°F) or 38 to 40°C (100 to
104°F).
2. Tone with occasional agitation for 8 to 45 minutes at
20°C(68°F), or for 2 to 15 minutes at 38 to 40°C (100 to
104°F).
Note: The toning action is so gradual that only a small
amount of agitation is necessary to prevent streaking.
Toning will occur in the highlights first and the shadows
last. Partial toning may produce blue highlights and
untoned shadows.
Wash fiber-base prints in running water at 18 to 24°C
(65 to 75°F) for at least 30 minutes; wash resin-coated prints
for 4 minutes.
